OF INDIANAPOLIS, INDIANA, ASSIGNOR TO LOUISA G. MORGAN, OF SAME PLAGE.

WELL-LINING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 257,046, dated April 25, 1882.`

(No model.)

To all whom it may concern:

Be it known that I, ALFRED W. MORGAN, a resident of Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvement i'n Apparatus for Lining Wells, et1 which the following is a specification, having reference to the accompanying drawings.

My invention relates to an improved mold 1o for forming a continuous cement or concrete lining for wells, my object being to construct a mold that will keep a definite size and shape while the concrete liningis forming, but which may be readily released after the concrete has become hardened.

My invention consists in the means of retaining the outside and inside of the mold in shape, and manner of operating it, as hereinafter fully described.-

In the accompanying drawings, Figure l is a perspective view of my invention. Fig. 2 is a top plan. Fig. 3 is a vertical section through 00 on Fig. 2.

Like letters refer to like parts in all gures. 2 5 A is the cylindrical tube, open at both ends,

and having the top end flared, as shown at u..

It is made of a sheet ot' metal rolled into tubular form, and having 'the edges ot the sheet overlapping, but not fastened permanently togather. Said edges are held together by means of a latch, D, which is pivoted to one edge of the sheet and'hooks over a projecting stud, e,

on the other edge, as shown in Fig. l. The free end of latch D is turned outward and engages the guard E when the latch is lifted ot't' the projecting stud e, thus limiting the expansion of the tube. The edges of sheet A are still further held in place by the cleats F F, which are riveted to one edge and overlap the 4o other edge, as shown. Within the tube A is another tube, B, similarly formed of a sheet of metal rolled together, but not flared at the top, and somewhat longer than A. Tube A is so rolled that the elasticity ot' the sheet tends to expand it, and tube Bis rolled so that it tends to contract. The central portion of tube B is braced and held rmly in shape by means of a metallic ring, H, which engages the peculiarly formed and arranged lugs h It', and having a 5o bail, H', for lifting it by. Said lugs are riveted to the interior of the tube, and are arranged alternately around the interior circumference, lugs It forming hooks tapering outward and lugs 7L tapering inward, so that as ring E is dropped into the tube the sheet is caused to closely conform to the shape of said ring. By using different-sized rings the tube B is made of different diameters, as may be required. The top of tube B :is steadied and held in place centrally within tube A by the braces b, 6o extending radially outward from B and resting against the interior and ou the top edge ot' A. An annular space is thus formed between tubes A and B, the top of which space is open and the bottom closed by a wooden ring, C, the outside diameter of which is the same as that of the tube A. rlhree or more short blocks, c, are fastened on the top ot ring` C. Said blocks till snugly between tubes A and B and serve to keep said tubes and rings C 7o in true relative position.

The operation of my invention is as follows: The tube A having been drawn together, the latch D engaging lug e, it is placed on ring C, and tubeB is placed in position centrally within tube A. The whole is now suspended over the mouth of the well by chains attached to the top edge of A, as shown, and suspended from a frame-work or derrick.- Ring C is held up against the bottom ofA by means of the bent 8o rods r r, suspended by chains o from a derrick in the usual manner, well-known in well-wall` ing apparatus. Cement concrete is now poured into the space between tubes A and B, iilling it nearly up to the daring-point at d. Said concrete is allowed to remain and harden until itA is selfsustaining. `When it has become hard the latch D is raised from lug e and the tube A expands, the expansion being limited by the guard E. The ring His new lifted out ot' cougo tact with the inclined lugs 7L and h, and tube B contracts, thus leaving the concrete-tube free from the mold. The ring G, carrying the new-formed section of concrete tubing, is new lowered by the derriclr into the well until the top edge of said concrete is near the bottom of the mold. rlhe mold is now readjusted and more concrete poured in, the process being repeated till ring C reaches the bottom of the well. Rods r r are now withdrawn, the ring roe C being` left nt the bottom of the Well. A 2..InoOn1bination Withthe Outward-expand smooth continuous lining` is thus formed Wthing tube A, the latch D, lug,` e, and guard E, out having to descend the Well. substantialy as and for the purpose set forth. 15
